VS1000 is a single-chip Ogg Vorbis (license-free

audio codec) player. VS1000 contains a high-per-

formance low-power DSP core VS DSP4, NAND

FLASH interface, Full Speed USB port, general

purpose I/O pins, SPI, UART, as well as a high-

quality variable-sample-rate stereo DAC, and an

earphone ampliï¬er and a common voltage buffer.

VS1000 ï¬rmware implements a default player that

reads and plays ï¬les from the NAND FLASH.

The player can be customized or replaced by us-

ing boot from NAND FLASH.

When connected to USB, the ï¬rmware implements

USB Mass Storage Device protocol or acts as an

Audio Device, providing a single-chip USB head-

phone application.

EarSpeaker spatial processing provides more nat-

ural sound in headphone listening conditions. It

widens the stereo image and positions the sound

sources outside the listenerâs head.

SPI EEPROM can be used to load code in appli-

cations that do not use NAND FLASH.
